For treatment of
500KV-1000KV high voltage, ultra-high voltage transformer oil, we recommend our
DVTP double stages High Vacuum Plant Purification Of Transformer Oil, it is widely
used in various types of large-scale transformer equipment installation and
maintenance, and also for purification of high-grade new oil, imported oil.
DVTP adopts double stages dehydration and degassing vessel, which can improve
dielectric strength soon. Meanwhile, it can be used as a separate vacuum source
of vacuum pumping and vacuum oiling.

3. The use of German
Leybold vacuum pump and roots pump can quickly improve the vacuum pressure. The
control interlock protection device, over-voltage alarm shutdown protection and
phase sequence protection to ensure a reliable long-term operation of the
machine
